Answer:

48/25 as an improper fraction, 1 23/25 as a mixed fraction.

Step-by-step explanation:

It is -8/5 divided by 5/-6.

First of all, you can get rid of the negative signs becasue there are two.  Negative and Negative equals positive, so we already know that the answer will be positive.  

So, we now have 8/5 divided by 5/6.

When you divide fractions, the fraction being divided is turned to it's reciprocal.  To get a fraction's reciprocal, just flip the numerator and denominator's places.  It's that easy!  

Here is an example:  2/3's reciprocal is 3/2.  The numbers just get flipped!

That would mean 5/6's reciprocal would be 6/5.  Don't find the reciprocal of 8/5 because it is not the number that is getting divided.  When you find a reciprocal you can change the division sign into a multiplying sign.

Example:  2/3 divided by 4/5.  Reciprocal of 4/5 is 5/4.  Now it is 2/3 <u>TIMES</u> 5/4.

Back to the problem.

We now have 8/5 <u>TIMES</u> 6/5.  When you multiply fractions, just multiply both numerators, in this case being 8 and 6, and the denominators, in this case being 5 and 5.  So 8 times 6 is 48.  5 times 5 is 25.

We now have 48/25, which can be reduced to 1 23/25!  

For the mixed number, if you are confused, 25 goes into 48 only one time.  So, the whole number is 1.  but when 25 goes into 48 only one time, there is still 23 left because 48-25= 23.  23 is our new numerator!  The denominator stays the same.  So, it's 1 23/25.  :)

Find the longer leg of the triangle.
Paha777 [63]

Answer:

Choice A. 3.

Step-by-step explanation:

The triangle in question is a right triangle.

  • The length of the hypotenuse (the side opposite to the right angle) is given.
  • The measure of one of the acute angle is also given.

As a result, the length of both legs can be found directly using the sine function and the cosine function.

Let \text{Opposite} denotes the length of the side opposite to the 30^{\circ} acute angle, and \text{Adjacent} be the length of the side next to this 30^{\circ} acute angle.

\displaystyle \begin{aligned}\text{Opposite} &= \text{Hypotenuse} \times \sin{30^{\circ}}\\ &=2\sqrt{3}\times \frac{1}{2} \\&= \sqrt{3}\end{aligned}.

Similarly,

\displaystyle \begin{aligned}\text{Adjacent} &= \text{Hypotenuse} \times \cos{30^{\circ}}\\ &=2\sqrt{3}\times \frac{\sqrt{3}}{2} \\&= 3\end{aligned}.

The longer leg in this case is the one adjacent to the 30^{\circ} acute angle. The answer will be 3.

There's a shortcut to the answer. Notice that \sin{30^{\circ}} < \cos{30^{\circ}}. The cosine of an acute angle is directly related to the adjacent leg. In other words, the leg adjacent to the 30^{\circ} angle will be the longer leg. There will be no need to find the length of the opposite leg.

Does this relationship \sin{\theta} < \cos{\theta} holds for all acute angles? (That is, 0^{\circ} < \theta?) It turns out that:

  • \sin{\theta} < \cos{\theta} if 0^{\circ} < \theta;
  • \sin{\theta} > \cos{\theta} if 45^{\circ} < \theta;
  • \sin{\theta} = \cos{\theta} if \theta = 45^{\circ}.

I am too lazy I'll explain so you find 688 minus 267 then you divide the difference by 6 and then u subtract the difference from 267x100 because that will be the total. Then u find the mean of the 94 numbers u get!
